Several comments/suggestions - Marker scaling, Google Satellite/Earth view, Multi-Level Folders

Hey Matt, thanks for all your work... after using caltopo as a subscriber for several months, there's a few things that came to the surface, that would enhance the way that I use it.

1. I've been avoiding using markers, because I like to have a nice clean overview of routes when I'm zoomed out, but the markers swamp everything else on the map. Wondering if it's possible to build in some scaling of objects based on the zoom level.

2. I like to draw my own routes by directly tracing the trails in google satellite view, but often the latest images were taken during a period of snow cover, thus obscuring the trails and features. Google Earth allows you to select historical images on a sliding date scale, and there's often a previous image that's free of snow, and the trails are clearly visible. Is it possible to incorporate not just Google Satellite, but Google Earth as a layer???

3. It would be really handy to create a multi-level folder structure, similar to a directory tree. For example, I'd like to have some routes that I've completed (which themselves are folders with multiple objects) in one folder, and future, planned routes in another. I'd like to avoid creating different maps, because I'd like them to be viewable at the same time.

Thanks!!!

    Hi Kevin -

    Thanks for the feedback.

    1. I'm unlikely to support this, since it's very specific to your use case - there are others who would want everything to show regardless of zoom level. However you can show and hide markers, as well as labels, on a folder-by-folder basis, which allows you to clean up the map display when zoomed out.

    2. This is unique to Earth and not an option that the Google Maps API supports.

    3. I've thought about this and may implement it at some point, but at the moment it would add a fairly large amount of complexity to my codebase. I'm also concerned about doing it in a way that isn't confusing for novice or less computer-savvy users.

    Matt, thanks for the reply... all of those explanations make perfect sense, and I anticipated that those might be the case.

    Anyway, it still blows me away what you've done with CalTopo... so thanks again. You may appreciate my comment to the recent CalTopo article on theoutbound.com ...Go check it out.

    Cheers!
